Windows 95 and 98 Troubleshooting

Review this section if any of the following problems occur:

•	Modem initialization errors occur when attempting to dial-out using a communications application.

•	The modem is not detected.

•	Connection fails or other problems occur.

It may be necessary to define a modem type within your communications application. If the Xircom modem is not listed, choose a "Generic Hayes compatible" device.

If your computer is equipped with an infrared communications port, you may need to disable this port. These ports often use COM port resources required for other communications devices. Disable the infrared port both in the computer's CMOS or BIOS setup program and the Windows Device Manager, as follows:

1	Some computers use a hardware setup utility to configure the infrared port in the BIOS. See your computer documentation.

2	To disable the infrared communications port in Windows, go to Device Manager tab under System in the Control Panel.

3	Double-click the Ports (COM & LPT) entry and the IR Serial Port entry. Remove the check mark under Device Usage. (Note: In Windows 95 version 950b or later check the Disable in this Hardware Profile option to disable the device.)

Use the Modem Diagnostics Tool to verify the computer-to-modem interface.

1	In the Modems option in Control Panel, click Diagnostics.

2	In Diagnostics properties, highlight the COM port associated with the Xircom modem and click the More Info button. This causes Windows to send commands to and read responses from the modem and display information about the modem and its COM port. The Port Information box should display the following information:

•	The IRQ and I/O address of the modem's COM port. These should match the physical configuration of the port or modem adapter.

•	Modem responses to various AT commands. The Xircom modem may return ERROR for some AT commands that are not supported. This does not indicate a failure.

3	A log file can be useful to help identify modem problems by recording modem commands and responses. Windows 95 and 98 have slightly different procedures for creating and maintaining a log file:

•	In Windows 95, go to Control Panel, Modems, Properties, Connection, Advanced. In the Advanced Connection Settings window, place a check mark in the Record a log file option box. A MODEMLOG.TXT file will be created in the C:\WINDOWS directory the next time the modem is used.

•	Windows 98 creates a log file by default in the Windows directory, using a filename based on the modem device identifier, with a .LOG extension, such as "Xircom_modem_56_globalaccess.log" (or a shortened version in MS-DOS). To continue adding information to the log file, place a check mark in the Append to Log option box in the Advanced Connection Settings window in the path Control Panel, Modems, Properties, Connection, Advanced.

Windows NT 4.0 Troubleshooting

Modem difficulties can usually be traced to interrupt, memory address or communications port conflicts. A modification to the Windows NT 4.0 default communication drivers or physical damage to card or cables can also be the source of problems.

Symptoms and Possible Causes

Windows NT or Xircom utility software fails to detect a Xircom modem. These conditions can be caused by the lack of an available COM Port, or by a resource conflict with another device.

Possible Solutions

1	Modify the interrupt and/or memory address for the Xircom card until no conflicts remain.

2	If your computer has an infrared communications port, disable it. These ports often use COM port resources required for other communications devices. Most infrared ports may be disabled from within the computer's CMOS or BIOS setup program. On some computers a hardware setup utility is used. See your computer documentation.

Sollte eines der nachfolgend beschriebenen Probleme auftreten, lesen Sie diesen Abschnitt bitte vollständig durch.

•	Beim Wählvorgang mit einer Kommunikationsanwendung kommt es zu einem Modeminitialisierungsfehler.

•	Das Modem wird nicht erkannt.

•	Verbindungsstörung oder sonstige Probleme.

Unter Umständen muß in Ihrer Kommunikationsanwendung ein Modemtyp angegeben werden. Falls das Xircom-Modem nicht aufgeführt ist, wählen Sie ein Hayes-kompatibles Gerät.

Wenn Ihr Computer über eine Infrarot-Schnittstelle verfügt, müssen Sie diese unter Umständen deaktivieren. Häufig verwenden diese Anschlüsse COM-Port-Ressourcen, die für andere Kommunikationsgeräte benötigt werden. Deaktivieren Sie den Infrarot-Port sowohl im CMOS- oder BIOS-Setup-Programm als auch im Geräte-Manager von Windows 95. Gehen Sie dabei folgendermaßen vor:

1.	Bei einigen Computern wird der Infrarot-Port mit Hilfe eines Hardware-Setup-Programms im BIOS konfiguriert. Informieren Sie sich diesbezüglich anhand Ihrer Computer-Dokumentation.

2.	Um den Infrarot-Kommunikationsport unter Windows 95 zu deaktivieren, klicken Sie in der Systemsteuerung auf "System" und anschließend auf "Geräte-Manager".

3.	Klicken Sie die Optionen "Anschlüsse (COM und LPT)" und "Serieller IR-Anschluß" doppelt an. Entfernen Sie die Markierung unter "Gerätenutzung". (Hinweis: Ab Windows 95-Version 950b müssen Sie die Option "Für dieses Hardwareprofil deaktivieren" markieren.)

2.	Markieren Sie anschließend den COM-Port, an dem das Xircom-Modem angeschlossen ist, und klicken Sie auf "Details...". Windows 95 sendet daraufhin Befehle an das Modem, registriert dessen Reaktion und zeigt Informationen über das Modem und den jeweiligen COM-Port an. Im Feld mit den Anschlußinformationen sollte folgendes erscheinen:

•	Die Interrupt- und I/O-Adressen des COM-Ports. Diese müssen mit der physikalischen Konfiguration des Ports oder des Modemadapters identisch sein.

•	Das Modem reagiert auf verschiedene AT-Befehle. Bei Befehlen, die vom Xircom-Modem nicht unterstützt werden, erscheint die Meldung ERROR. Dies weist jedoch nicht auf eine Fehlfunktion hin.

3.	Eine Protokolldatei, in der Modembefehle und -reaktionen aufgezeichnet werden, kann bei der Erkennung von Modemproblemen hilfreich sein. Windows 95 und 98 weisen etwas unterschiedliche Verfahren bei der Erstellung und Pflege einer Protokolldatei auf:

•	Unter Windows 95 rufen Sie nacheinander auf "Systemsteuerung", "Modems", "Eigenschaften", "Einstellungen" und "Erweitert". Markieren Sie im Fenster "Erweiterte Einstellungen für Modem" das Feld "Protokolldatei aufzeichnen". Dadurch wird bei der nächsten Benutzung des Modems im Verzeichnis C:\WINDOWS eine Datei mit dem Namen MODEMLOG.TXT erstellt.

•	Unter Windows 98 wird eine Protokolldatei standardmäßig im Windows-Verzeichnis erstellt, wobei ein auf der Modemidentifikation basierender Dateiname mit der Erweiterung .LOG gewählt wird, wie beispielsweise "Xircom_modem_56_globalaccess.log" (oder in einer kürzeren Version unter MS-DOS).

Italiano: Risoluzione di problemi in ambiente Windows 95 e 98
Risoluzione di problemi in ambiente Windows 95 e 98

Consultare questa sezione nel caso in cui dovesse presentarsi uno dei seguenti problemi:

•	Errori di inizializzazione del modem che intervengono quando si compone un numero con una applicazione di comunicazione.

•	Il modem non viene rilevato.

•	Il collegamento non viene stabilito o si presentano altri problemi.

Potrebbe essere necessario specificare il tipo di modem utilizzato nell'applicazione di comunicazione. Se il modem Xircom non compare nella lista, selezionare un modello "Compatibile Hayes standard".

Se il computer dispone di una porta di comunicazione a raggi infrarossi, potrebbe essere necessario disabilitarla. Queste porte utilizzano spesso le risorse della porta COM necessarie per altri dispositivi di comunicazione. Disabilitare la porta ad infrarossi sia nel CMOS del computer o nel programma di configurazione del BIOS, sia nella Gestione periferiche di Windows 95 procedendo nel seguente modo:

1	Alcuni computer utilizzano una utilità di configurazione hardware per configurare la porta a raggi infrarossi nel BIOS. Consultare la documentazione del proprio computer.

2	Per disabilitare la porta di comunicazione ad infrarossi in Windows 95, selezionare l'icona Sistema nel Pannello di controllo e quindi la scheda Gestione periferiche.

3	Fare un doppio clic sulla voce Porte (COM e LPT) e poi su Porta seriale IR. Rimuovere il segno di spunta in Utilizzo della periferica. (Nota: Nella versione 950b o successive di Windows 95 spuntare l'opzione Disabilita in questo profilo hardware per disabilitare il dispositivo.)

Utilizzare lo Strumento di diagnostica del modem per controllare l'interfaccia computer-modem.

1	Nel Pannello di controllo selezionare l'icona Modem, quindi fare clic sulla scheda Diagnostica.

2	Nella scheda Diagnostica, evidenziare la porta COM associata al modem Xircom e fare clic sul pulsante Informazioni addizionali.... In questo modo Windows 95 invia comandi al modem e ne legge le risposte visualizzando le informazioni relative al modem ed alla porta COM ad esso associata. La finestra Informazioni addizionali... dovrebbe mostrare le seguenti informazioni:

•	Il numero di Interrupt IRQ e l'indirizzo di I/O della porta COM del modem. Queste informazioni dovrebbero corrispondere alla configurazione fisica della porta o della scheda modem.

•	Le risposte del modem ai diversi comandi AT. Il modem Xircom potrebbe dare come risposta un ERROR per alcuni comandi AT che non sono supportati. Questa eventualità non sta tuttavia a significare un malfunzionamento del modem.

3	La creazione di un file di registro potrebbe aiutare ad identificare i problemi relativi al modem, registrando i comandi e le risposte di questo dispositivo. Windows 95 e 98 richiedono una procedura leggermente differente per la creazione e la manutenzione del file di rapporto:

•	In Windows 95, nel Pannello di controllo selezionare l'icona Modem, quindi fare clic sul pulsante Proprietà, selezionare la scheda Connessione e fare clic sul pulsante Avanzate. Nella finestra Impostazioni di connessione avanzate, spuntare la casella Crea file registro. In questo modo, al successivo utilizzo del modem, verrà creato un file MODEMLOG.TXT nella directory C:\WINDOWS.

•	Windows 98 crea un file di rapporto nella directory Windows, e gli assegna un nomefile basato sull'identificatore del dispositivo modem, con estensione .LOG, ad esempio "Xircom_modem_56_globalaccess.log" (o in una versione più compatta nel caso di MS-DOS). Per continuare a registrare informazioni in questo file, spuntate la casella Appendi al file registro nella finestra Impostazioni di connessione avanzate nel Pannello di controllo del path, Modem, Proprietà, Connessione, Avanzate.

Risoluzione di problemi in ambiente Windows NT 4.0

Le difficoltà che si possono incontrare nell'uso di un modem sono generalmente legate a conflitti di interrupt, indirizzo di memoria o porta di comunicazione. E' anche possibile riscontrare problemi correlati alla modifica dei driver di comunicazione predefiniti di Windows NT 4.0, od a danni fisici alla scheda od ai cavi di connessione.

Sintomi e possibili cause

Windows NT o il software delle utilità di Xircom non è in grado di rilevare il modem Xircom. Queste condizioni d'errore possono essere causate dall'assenza di una porta COM disponibile, o da un conflitto di risorse con un altro dispositivo.

Possibili soluzioni

1	Modificare l'interrupt e/o l'indirizzo di memoria della scheda Xircom fino all'eliminazione del conflitto.

2	Se il computer è provvisto di una porta di comunicazione ad infrarossi, disabilitare questa periferica. Queste porte utilizzano spesso le risorse della porta COM necessarie ad altri dispositivi di comunicazione. La maggior parte delle porte ad infrarossi possono essere disabilitate tramite il programma di configurazione BIOS o CMOS. Alcuni computer rendono disponibile un programma d'utilità per la configurazione hardware. Per questi aspetti, consultare la documentazione allegata al computer

3	Per problemi legati alla connessione a siti particolari, quali il Provider del servizio Internet, od a punti di accesso remoto societari, verificare con il personale tecnico se il software client ed il programma per le sessioni di comunicazione remota sono configurati correttamente.

English: Standard AT Commands Modified for GSM
Standard AT Commands Modified for GSM

The following commands are implemented for GSM data transmission and are functionally different from the corresponding standard AT commands. Use the GSM version of these commands for GSM data calls.

Dn	Dial A Telephone Number

The ATDn command is used to dial a telephone number. The n represents a dial string consisting of dial digits/characters and dial modifiers (see below) and must not exceed 40 characters. Spaces, hyphens, and parentheses can be used for clarity, but they are ignored by the modem.

Dialing digits/characters required for GSM are 0 - 9 * # + A B C D. Dial modifiers for GSM are listed here:

Dial Modifiers

Dial modifiers are recognized by the modem only when they are part of a dial string following the ATD command.

The following dial modifiers are used with GSM:

I	ISDN Interworking

The I modifier must immediately precede the telephone number. It specifies that the interworking function (IWF) to be used for originating the GSM data call is ISDN, providing for unrestricted digital information. Without the I dial modifier, the default interworking function is the Public Switched Telephone Network (PSTN).

L	Redial Last Number

Redials last number if used as first character following ATD. Otherwise it is ignored.

S=n	 Dial a Stored Telephone Number

The S modifier instructs the modem to dial a number that had been previously stored by the use of the AT&Zn=x command. The command to dial a stored telephone number is ATDS=n, where n represents telephone number storage location 0 or 1. For example, ATDS=1, dials the telephone number written to telephone number storage location 1.

+	Foreign Exchange Access

The plus sign (+) dial modifier must be the first character in the telephone number. It requests access to the foreign exchange of the mobile phone network, for initiating a call from one country to another via GSM.

;	Return to Command Mode after Dialing

The semicolon (;) dial modifier can be used only at the end of a command line, immediately preceding the Enter, and instructs the modem to return to the command mode immediately after dialing and without breaking the connection with the distant modem.

The following dial modifiers are implemented for Xircom GSM products, and will be accepted for compatibility, but are ignored:

P	Pulse Dialing Method

The P modifier is used with the Dial command to instruct the modem to pulse dial the telephone number that follows.

T	Tone Dialing Method

The T modifier is used with the Dial command to instruct the modem to tone dial the telephone number that follows. See also the ATT command.

W	Wait for Second Dial Tone

The W modifier instructs the modem to wait for a dial tone before processing the remaining characters in the dial string.

,	Delay Processing the Next Character

When the comma (,) modifier is included as part of the dial string following the ATD command, the modem pauses before processing the next character in the dial string. The duration of the pause is dictated by the contents of S-Register S8.

!	Hook Flash

The exclamation point (!) modifier serves as a switch hook (or hook flash) signal. This causes the modem to hang up (go on-hook) for about 0.5 seconds then return to off-hook (the actual duration of the hook flash varies in different countries).

@	Wait for Quiet Answer

The at sign (@) modifier in a dial string instructs the modem to wait for five seconds of silence after dialing the number. If silence is not detected, the modem sends a NO ANSWER result code to the user.

H	Switch Hook Options

The ATH causes the modem to go on-hook (hang up).

In	Request ID Information

The ATI command has various options which are used to instruct the modem to provide specific information about itself.

I1	Calculates ROM checksum and displays it on the DTE (for example, 12AB)

I2	Performs a ROM check and calculates and verifies the checksum, displaying OK or ERROR.

I3	Displays modem firmware revision information

&Fn	Load Factory Settings

The AT&F command loads factory default parameters from ROM into the active configuration profile, replacing the parameters stored there. This command must be issued by itself. If it is used with another AT command, its function will be ignored.

&F0	Recall factory settings as active configuration

\Nn	Error Mode Control Selection

The AT\Nn command sets the type of error correction supported by the modem when sending or receiving data. Note: the AT\Nn commands affect the +CBST settings.

\N0	Transparent buffered mode. No error correction (same as &Q6).

\N1	Transparent buffered mode (same as \N0).

\N2	Non-Transparent (RLP) mode. The modem attempts to connect in RLP mode. If this fails, the call will be disconnected.

If after issuing the \N2 command, the connection element <ce> is changed to Transparent (+CBST=<speed>,<name>,<ce> where <ce> is set to 0), the modem attempts to connect using MNP error correction. If this fails the modem disconnects.

\N3	Non-Transparent mode (RLP) (default). The modem attempts to connect in RLP mode. If this fails, the call will be disconnected.

If after issuing the \N3 command, the connection element <ce> is changed to Transparent (+CBST=<speed>,<name>,<ce> where <ce> is set to 0), the modem attempts to connect using MNP error correction. If this fails, the modem connects in buffered mode without error correction.

 \N4	Non-Transparent mode (RLP). The modem attempts to connect in RLP mode. If this fails, the call will be disconnected.

\N5	Transparent MNP mode. The modem attempts to connect using MNP error correction. If this fails, the modem disconnects. This is also known as MNP reliable mode.

English: Guidelines for GSM Communications
Guidelines for GSM Communications

GSM communications require the Xircom GSM Connection Kit™ accessory to connect your GSM wireless phone to your Xircom GlobalACCESS modem. Search for "GSM" at www.xircom.com.

For best results sending data through your GSM connection, use the following guidelines:

1	Be sure that the GSM phone battery is adequately charged. No power is supplied to the GSM phone from the Xircom modem.

2	Be sure your GSM subscription includes all the data, fax, and message services you wish to use.

3	Be sure your GSM phone supports connection to PC Card (PCMCIA) adapters and is properly configured for the data, fax, and short message services to which you subscribe. Consult your GSM service provider and the user documentation supplied with your phone for assistance with the programming procedures to be used.

4	Some communications applications may require special setup strings in order to operate with a GSM telephone. Consult the documentation for your application. See AT Command Extensions for GSM for detailed information on communication commands and other technical matters.

5	For best results, stay in one location during a GSM data session.

6	Do not attempt data or fax transmissions from a moving vehicle.

7	If possible, position the phone with its antenna in a vertical position and located away from the computer and from any large metal objects or moving persons or objects. If calling from inside a building, a stronger signal may be available near a window.

8	For updated information, consult the README file on the Xircom Diskette or search for "GSM" on the Xircom website at www.xircom.com.


English: GSM Features Supported
GSM Features Supported

GSM communications using your GSM phone with the Xircom GSM Connection Kit™ accessory and your Xircom GlobalACCESS modem include the following features:

Data transfer

At present it is possible to transfer data over the GSM network at speeds up to 9600 bps. The GSM network will route the data call through its Interworking Function (IWF) to the remote terminal. In fact, the IWF acts as a gateway between the GSM network and other types of networks (like PSTN and ISDN). Once the connection between the mobile user and the remote terminal is established, data can be transmitted over the link.

There are two different asynchronous data services implemented:

• Transparent Service. Allows for end-to-end error correction and data compression (MNP2 and MNP5).

• Non-Transparent Service. Uses RLP (Radio Link Protocol) for error correction and V.42bis (may not be available in all networks) for compression on the GSM radio link.

One of the advantages of GSM is its compatibility with ISDN.  If the ISDN terminal adapter at the remote site supports V.110 (ISDN rate adaptation), it is possible to set up a data call between a GSM terminal and an ISDN terminal adapter. This will allow GSM users to set up a call in less then 5 seconds.

Fax

A fax call is similar to a data call. The fax call is routed through the IWF to the remote fax machine. Facsimile operation conforms to the Class 1 standard. Class 2 support is under development and will be added in the near future.

Short Message Service

The Short Message Service is a way to send and receive text messages of up to 160 characters with your GSM handset. You can use specialized software (like Trio Wireless Office) to type these SMS messages, instead of typing them on the handset itself.

The Xircom PC Card supports the Short Message Service (SMS) according to ETSI (GSM) 07.07.

Phonebook

It is possible to edit your mobile phone's phonebook from your portable PC.

This can be done with applications  which are compatible with the ETSI (GSM) 07.05 AT command set.


Modem AT Commands

With the exception of the Special Commands described at the beginning of the Command Reference, all commands must be preceded by the AT attention code (or command prefix) and terminated by pressing the Enter key.

The modem responds with the result code OK, which means it understands and can execute the command, or with ERROR, which means that the modem does not understand the command or that the command is invalid.

The modem must be in command mode when any command other than the online escape sequence is entered. Commands entered when the modem is in online mode are treated as data and transmitted as such to the modem at the other end of the line.

Some commands are used in coordination with S-Registers.

For modem script files to be used with popular communications packages, see the directory \SCRIPTS and the file SCRIPTS.TXT on the Xircom disk or in a downloaded Xircom software package.

Special Commands

+++ 	Online Escape Sequence

The escape sequence is used to switch to command mode from online mode during a session with a remote modem. Type three plus signs. The escape sequence is not preceded by the AT command prefix, nor does it require the Enter key. The setting of S-Register S2 determines the ASCII character used. S2=43 is the default (the + sign). 0-127 are valid. To disable the command, set S2 to a value greater than 127. Use the ATO (AT and letter oh) command to return to online mode.

Insert a pause before and after the escape sequence to prevent misinterpretation of the escape sequence as data. Use S-Register S12 to set the length of the pause.

A/	Repeat Last Command

The A/ command causes the modem to repeat the last command string. The command executes as soon as / is typed. It does not require the AT command line prefix, nor does it need to be followed by Enter.

AT Command Reference

A 	Answer

Typing ATA causes the modem to go off-hook and respond to an incoming call by generating a carrier signal and starting the handshaking process. This must be the only command or the final command in the command line.

If the handshaking process is successful and a connection is established, the normal CONNECT message is displayed. If the carrier signal is not detected within the time specified in S-Register S7, a NO CARRIER result code is displayed.

Bn	Select Communications Standard

The ATBn command selects the communication standard (ITU or Bell) to be used by the modem, as follows:

B0	Use ITU V.22 at 1200bps. B0 selects ITU V.22 at 1200bps and ITU V.21 at 300bps.

B1	Use Bell 212A at 1200bps. B1 selects Bell 212A at 1200bps and Bell 103J at 300bps.

B2	Unselect V.23 reverse channel.

B3	Select V.23 reverse channel.

B15	Selects V.21 when the modem is at 300bps (same as B0).

B16	Selects Bell103J when the modem is at 300bps (same as B1).

The ATB1 and ATB16 parameter settings are not available in some countries. Defaults are country-specific.

Break (Escape) command

See Special Commands at the beginning of this Command Reference section.

Cn	Carrier Control

The ATCn command, where n is 1, guarantees backward compatibility with communications software that issues the C1 command. C0 is not supported; it may set some modems to "receive only mode."

C0	Transmit carrier always off (not supported).

C1	Normal transmit carrier switching.

Dn	Dial A Telephone Number

The ATDn command is used to dial a telephone number. The n represents a dial string consisting of dial digits/characters and dial modifiers (see below) and must not exceed 40 characters. Spaces, hyphens, and parentheses can be used for clarity, but they are ignored by the modem.

The Dial command can be used for either pulse (rotary) or tone dialing. The dial digits/characters are 0 - 9 A B C D # *. The characters A B C D and the symbols # and * represent specific tone pairs and can be used only when tone dialing. These characters and symbols are ignored when pulse dialing is used. Some countries restrict or prohibit the use of some of these characters.

Dial Modifiers

Dial modifiers are recognized by the modem only when they are part of a dial string following the ATD command. Possible dial modifiers are:

L	Redial Last Number

Redials last number if used as first character following ATD. Otherwise it is ignored.

P	Pulse Dialing Method

The P modifier is used with the Dial command to instruct the modem to pulse dial the telephone number that follows.

S=n	Dial a Stored Telephone Number

The S modifier instructs the modem to dial a number that had been previously stored by the use of the AT&Zn=x command. The command to dial a stored telephone number is ATDS=n, where n represents telephone number storage location 0 or 1. For example, ATD P S=1 pulse dials the telephone number written to telephone number storage location 1.

,	Delay Processing the Next Character

When the comma (,) modifier is included as part of the dial string following the ATD command, the modem pauses before processing the next character in the dial string. The duration of the pause is dictated by the contents of S-Register S8.

The , modifier is frequently inserted after the digit (usually 9) used to obtain an outside line from a PBX to allow sufficient time for the dial tone to occur before the modem dials the telephone number. The W modifier can be used in place of the comma.

Some countries place restrictions on the amount of time a modem may delay during dialing.

T	Tone Dialing Method

The T modifier is used with the Dial command to instruct the modem to tone dial the telephone number that follows. See also the ATT command.

W	Wait for Second Dial Tone

The W modifier instructs the modem to wait for a dial tone before processing the remaining characters in the dial string.

!	Hook Flash

The ! modifier serves as a switch hook (or hook flash) signal. This causes the modem to hang up (go on-hook) for about 0.5 seconds then return to off-hook (the actual duration of the hook flash varies in different countries).

@	Wait for Quiet Answer

The @ modifier in a dial string instructs the modem to wait for five seconds of silence after dialing the number. If silence is not detected, the modem sends a NO ANSWER result code to the user.

;	Return to Command Mode after Dialing

The semicolon (;) dial modifier can be used only at the end of a command line, immediately preceding the Enter, and instructs the modem to return to the command mode immediately after dialing and without breaking the connection with the distant modem.

^	Disable Data Calling Tone Transmission

The ^ modifier in a dial string disables data calling tone for the current call (calling tone is automatically enabled in many countries). This modifier is not available in all countries.

$	Credit Card Tone Detect

The $ modifier in a dial string instructs the modem to wait for a credit card bong tone before processing the remaining characters in the dial string.

En	Echo Command

The ATEn command, where n represents 0 or 1, determines if the commands you issue through the keyboard to the modem in command mode are displayed (echoed) on your computers monitor screen.

E0	Disable echo to the computer

E1	Enable echo to the computer (default)

If the commands you type are not displayed on your monitor screen, your software is set to expect character echo from the remote system. You can remedy this by typing in the command ATE1. If the commands you type are displayed on your monitor with the characters duplicated, LLIIKKEETTHHIISS, type in the ATE0 command.

Hn	Switch Hook Options

The ATHn command hangs up the modem or prepares it for dialing.

ATH0	Causes the modem to go on-hook (default).

ATH1	Causes the modem to go off-hook (this command is restricted in some countries).

In	Request ID Information

The ATI command has various options which are used to instruct the modem to provide specific information about itself.

I0	Displays modem controller firmware revision (same as I3)

I1	Calculates ROM checksum and displays it on the DTE (for example, 12AB)

I2	Performs a ROM check and calculates and verifies the checksum. displaying OK or ERROR.

I3	Displays modem firmware revision information

I12	Returns country code (for example, North America)

Ln 	Monitor Speaker Volume

The ATLn command, where n represents 0, 1, 2, or 3, is listed here for backward compatibility reference only. The volume of the monitor speaker is controlled by the laptop computer, not by the modem.

Mn 	Speaker On/Off Selection

The ATMn command, where n represents 0, 1, 2, or 3, enables or disables the transmission of sound signals from the modem to the computer speaker. (Sound production also requires that the computer speaker be enabled.)

M0	Speaker always off.

M1    	Speaker on until data carrier is detected

M2	Speaker always on when modem is off-hook

M3	Speaker off as digits are dialed, then on after dialing until data carrier is detected

Nn	Negotiation of Handshaking Options

The ATNn command, where n represents 0 or 1, determines whether or not the sending modem performs a negotiated handshake when the speed of the answering modem is different from that of the sending modem.

N0	When originating or answering, handshake only at the communication standard specified by the contents of S-Register S37 and the ATBn command option selected.

N1	When originating or answering, handshake only at the communication standard specified by the contents of S-Register S37 and the ATBn command option selected. During handshaking, fall back to a lower speed, if required. (default)

On	Online Command

If the modem has been switched to command mode, typing in the ATO0 command will return it to the online mode with the existing connection.

O0	Instructs modem to leave online command mode and return to data mode (see +++ Escape Sequence under Special Commands)

O1    	This setting issues a retrain command before returning to online data mode.

O2	This setting issues a rate negotiation command before returning to online data mode.

P	Select Pulse Dialing

The ATP command instructs the modem to use pulse (rotary) dialing. This mode will remain in force for all dialing procedures unless an ATT command is issued or the dial string contains a T dial modifier.

Qn	Result Code Display Options

The setting of the ATQn command, where n represents 0 or 1, determines whether or not result codes (such as OK, CONNECT, RING, NO CARRIER, and ERROR) are displayed on your PCs screen.

Q0	Display of result codes enabled.

Q1	Display of result codes disabled.

Repeat command

See Special Commands at the beginning of this topic.

T	Select Tone Dialing

The ATT command instructs the modem to use tone dialing. This mode will remain in force for all dialing procedures unless an ATP command is issued or the dial string contains a P dial modifier. Tone dialing is the factory-default setting.

Vn	Result Code Format Options

The ATVn command, where n represents 0 or 1, determines if result codes are displayed as numeric (short form) codes or words (long form). Numeric result codes contain only one or two digits and this form could be used, for example, when the modem is controlled by a software terminal emulation program that uses script files. See the list at the beginning of this topic showing result codes in both long and short formats.

Type the command ATV or ATV0 to select numeric result codes. The factory default is to display the result codes as words (ATV1). You should issue an ATV1 command either to reset the factory default after a change has been made or to select the long-form (word) result codes. Negotiation progress messages (extended result codes) are those with a numerical value of 40 or more.

Four other AT commands, two dial modifiers, and an S-Register are also directly involved in the generation and display of result codes. These are the ATQn, ATVn, ATWn, and ATXn commands, the ATDW and ATD@ dial modifiers, and S-Register S95.

Wn	Negotiation Progress Message Selection

The ATWn command, where n represents 0, 1, or 2, works in conjunction with S-Register S95 to determine how that subset of the result codes  called negotiation progress messages or extended result codes  will be used to report the type of connection, protocol, and other communication techniques that resulted from handshaking and subsequent negotiation.

The options available to represent n in the ATWn command are:

W0 	CONNECT result code reports DTE speed. If S-Register S95=0, disable the display of all extended result codes.

W1	CONNECT result code reports DTE speed. If S-Register S95=0, enable the display of CARRIER and PROTOCOL extended result codes only.

W2 	CONNECT result code reports DCE (modem-to-modem) speed. If S-Register S95=0, disable the display of all extended result codes.

Xn	Result Code Set/Call Progress Option

The ATXn command, where n represents 0-4, controls how the modem responds to dial tone and busy signals and how it displays CONNECT result codes. The options available to specify with the ATXn command are:

X0	Result codes 0-4 enabled. Busy detect and dial tone detect disabled.

X1	Result codes 0-5, and 10 enabled. Busy detect and dial tone detect disabled.

X2	Result codes 0-6, and 10 enabled. Busy detect disabled and dial tone detect enabled.

X3	Result codes 0-5, 7, and 10 enabled. Busy detect enabled and dial tone detect disabled.

X4	Result codes 0-7, and 10 enabled. Busy detect and dial tone detect enabled.

Some countries do not allow busy detect or dial tone detect to be disabled.

&B1 	Enables the V.32 automatic retrain capability (supported for backward compatibility only).

&Cn	Data Carrier Detect (DCD)

The AT&Cn command, where n represents 0 or 1, selects the method by which the modem handles the carrier detect signal.

&C0	The carrier detect signal is forced on regardless of the condition of the distant modems carrier.

&C1	The state of the carrier from the remote modem is monitored. The local modems DCD signal is on when the remote modems carrier signal is detected, and off when it is not (default).

&Dn	Data Terminal Ready (DTR) Options

The AT&Dn command, where n represents 0-3, controls how the Data Terminal Ready (DTR) signal is used by the modem.

&D0	Ignore the DTR signal from the computer and treat it as always on.

&D1	Monitor DTR and, when an ON-to-OFF transition of the DTR signal occurs, switch to command mode, issue an OK result code, and remain connected.

&D2	Monitor DTR and, when an ON-to-OFF transition of the DTR signal occurs, hang up the line and switch to command mode.

&D3	Monitor DTR and, when an ON-to-OFF transition of the DTR signal occurs, hang up, reset the modem and switch to the initialization state.

&Fn	Load Factory Settings

The AT&F command loads factory default parameters from ROM into the active configuration profile, replacing the parameters stored there. This command must be issued by itself. If it is used with another AT command, its function will be ignored.

&F0	Recall factory settings as active configuration

+MS	Modulation Selection

The AT+MS command is not applicable under the V.90 standard for 56K modems.

The AT+MS parameter controls data modulations and bit rates that may be negotiated between a local and remote modem. It accepts four subparameters.

Syntax:	AT+MS=<carrier>,<automode>,<min_rate>,<max_rate>

AT+MS?

AT+MS=?

+MS?	Reports the current settings of subparameters

+MS=?	Displays range of acceptable values for each subparameter

<carrier>	Specifies the preferred modulation to be used in originating or answering a connection. The <carrier> subparameter is an unquoted string of characters. If the <carrier> parameter is specified, the other subparameters will revert to factory defaults. If <carrier> is omitted, any unspecified parameters will keep their current values (for example, AT+MS=,0 or AT+MS=,,,2400).

Values accepted for <carrier> are the following:

B103	Bell 103 (300bps)

B212	Bell 212A (1200bps)

V21	ITU-T V.21 (300bps)

V22	ITU-T V.22 (1200bps)

V22B	ITU-T V.22bis (2400bps)

V23C	ITU-T V.23 with constant carrier (1200/75 or 75/1200bps)

V32	ITU-T V.32 (4800 or 9600bps)

V32B	ITU-T V.32bis (4800 - 19200bps)

V34	ITU-T V.34 (2400 - 33600bps)

K56	(default) Lucent/Rockwell K56flex (32000 - 56000bps)

<automode>	Enables or disables negotiation of an alternative <carrier> if the preferred modulation is not available.

Values accepted for <automode> are the following:

0	Disabled. Modem will disconnect if it is unable to negotiate a connection with the specified <carrier>.
1	Enabled (default). If the specified <carrier> is unavailable, modem will attempt to negotiate an alternative carrier as appropriate.
<min_rate>	Specifies the lowest bit rate at which the modem may establish a connection. (This value is fixed at zero for the Xircom modem.)
<max_rate>	Specifies the highest bit rate at which the modem may establish a connection. For modulations that support only a fixed bit rate (such as V.22bis), <max_rate> has a fixed value to which it defaults. If the default rate or a rate other than zero is specified, the modem will return ERROR. This subparameter accepts the following values: 0, 300, 1200, 2400, 4800, 7200, 9600, 12000, 14400, 16800, 19200, 21600, 24000, 31200, 33600bps. If unspecified (set to 0), <max_rate> is determined by the value of <carrier>.
	If the <carrier> setting is K56, the <max_rate> subparameter should be left at the default value (zero).

Modem S-Registers

Introduction to S-Registers

The Xircom modem uses memory storage locations, or S-Registers, to hold information controlling its operating environment. Few of these S-Registers require attention from modem users. S-Registers are used in conjunction with AT commands .

To display the value of an S-Register, type ATSn? where n is the number of the S-Register, then press Enter.

To modify the value of an S-Register, type ATSn=r where n is the S-Register number and r is the new value or setting, then press Enter.

S-Register Reference

S0	Ring to Answer After

The contents of register S0 sets the number of rings required before the modem goes off-hook to answer an incoming call (auto answer). The value can range from 0 to 255. ATS0=0 disables the auto-answer function. The default is 0.

S1	Ring Counter

This register is read only. The value of S1 increments with each ring. If no rings occur over a six-second interval, the register is cleared. The value of S1 can range from 0 to 255. The default is 0. There may be country-specific limits.

S2	AT Escape Character

Register S2 defines the ASCII character used in the Escape sequence. This command is used to return to command mode without losing the connection with a remote modem. Default is S2=43, which is the "+" character. Thus the default Escape sequence is +++. ASCII values 127 and below can be used. To disable this Escape sequence, set S2 equal to a value greater than 127.

S3	Command Line Termination Character

This register contains the ASCII value of the command line terminating character (carriage return). The factory default value is ASCII 13 — the carriage return character. You can set register S3 to any value between 0 and 127.

S4	Response Formatting Character

This register contains the ASCII value of the line feed character. The factory default value is 10. You can set register S4 to any value between 0 and 127. The modem uses a line feed character in command mode when it responds to the computer.

S5	Command Line Editing Character

This register contains the ASCII value of the backspace character and is applicable to asynchronous transmissions only. The factory default value is 8. You can set register S5 to any value between 0 and 32, or to 127. The modem will not recognize the backspace character if it is set to a value greater than ASCII 32.

S6	Wait Before Blind Dialing

This register determines how long the modem waits after going off-hook before dialing the first digit. The wait must be at least 2 seconds. Register S6 can be set to any value between 2 and 65 seconds. The default is 2 seconds. The value of the W dial modifier will override the value in register S6. This operation, however, may be affected by some ATX options according to country restrictions. There may be country-specific defaults and limits.

S7	Connection Completion Time-Out

This register determines the number of seconds the originating modem waits for a carrier signal from the answering modem before hanging up. The timer is started when the modem finishes dialing (originate), or goes off-hook (answer). In originate mode, the timer is reset upon detection of an answer tone if allowed by country restriction. The timer also specifies the wait for silence time with the @ dial modifier (in seconds). S7 is not associated with the W dial modifier. Register S7 can be set at from 1 to 255 seconds with a default of 50 seconds. There may be country-specific defaults and limits.

S8	Duration of Pause for Comma Dial Modifier

This register determines the number of seconds to pause for each comma (,) in a dial string or command line. The default is 2 seconds, but any value from zero to 65 is acceptable. Defaults and limits are country-specific.

S10	Delay Between Lost Carrier/Hang Up

This register specifies the time (in tenths of a second) that the modem waits after carrier loss before hanging up. The default is 20 (2.0 seconds). Register S10 will accept a value ranging from 1 to 254 in tenths of a second (0.1 to 25.4 seconds). There may be country-specific defaults and limits.

S11	DTMF Tone Duration

This register determines the "touch tone" dialing speed which is prefixed for each country. The value can range from 50 to 150 milliseconds. The default is 95 milliseconds. The value of register S11 has no effect on pulse dialing. There may be country-specific defaults and limits.

S12	Escape Guard Time

This register sets the value (in 20 ms increments) of the required pause after the escape sequence. Range is 0 = 255, default is 50 units of 0.02 seconds each, or one second.

S28	V.34 Modulation Enable/Disable

This register enables or disables V.34 modulation. Default setting is 1, valid values are 0 or 1. A value of zero disables V.34 modulation. Any other value in the range enables it.

S30	Inactivity Timer

The value specified by this register sets how long the modem will wait (in minutes) before disconnecting when no data is sent or received. This function is only applicable in buffer mode.  It is set by AT\Tn. Values are 0-255. Default is 0 (disabled).

S34	DTE Throughput Limit

This register specifies whether the modem should limit throughput when the DTE is operating at higher speeds (57,600 or 115,200bps)

S34=0	Do not limit throughput (default).

S34=1	Limit throughput to DTE speed.

S35	Data Calling Tone

This register enables or disables a tone of a certain frequency and cadence as specified in V.25 that allows remote data/fax/voice discrimination. It is set by AT-Cn. The frequency is 1300 Hz with a cadence of 0.5 seconds on and 2 seconds off. The default is country-specific. Some countries do not allow data calling tone to be overridden.

S35=0	Data calling tone disabled (default)

S35=1	Data calling tone enabled

S36	Negotiation Fallback

This register specifies the action to be taken in the event of a negotiation failure when error control is selected.

S36=0,2	Hang up

S36=1,3	Fall back to an asynchronous connection

S36=4,6	Attempt MNP. If MNP fails, hang up.

S36=5,7	Attempt MNP. If MNP fails, fall back to asynchronous connection. Default is 7.

S37	Dial Line Rate

S37=0	Maximum modem speed (default)

S37=1	Reserved

S37=2	1200/75bps

S37=3	300bps

S37=4	Reserved

V.32bis and V.22bis auto rate is disabled. Retrain operation is disabled or enabled in date mode, and fallback is disabled in data mode.

S42=0	Auto rate disabled

S42=1	Auto rate enabled (default)

S43	Auto Mode

V.32bis startup auto mode operation disabled.

S43=0	Auto mode disabled

S43=1	Auto mode enabled (default)

S46	Data Compression Selection

The setting of this register is used to turn data compression on or off. It is set by AT%Cn.

Data compression can only be enabled when the modem is operating in an error-control (EC) mode using either V.42 LAP-M or MNP protocols.

S46=0	Modem will not attempt negotiation for data compression

Windows 3.x Modem Configuration Notes

The Xircom modem features Hayes and Microcom compatibility and the latest in data transmission, data compression, and error control techniques. It can be used with most standard communications and fax software packages.

Note

Unless Card and Socket Services are being used under Windows 3.x, the Xircom modem requires that the modem driver (CMENABLE.COM) be loaded before the modem can be used.

For more detailed modem information, see Modem Reference.

Using Modem Communications under Windows 3.x

Installing Communications and Fax Software

The Xircom modem is compatible with most popular communications and fax software packages. See the directory \SCRIPTS on the Xircom diskette for configuration assistance.

Running Windows Communications and Fax Software

Windows 3.x-based fax and communications programs can be started immediately once the modem has been initialized.

Running DOS Communications and Fax Software

DOS-based communications software should be run from a DOS prompt without Windows loaded. DOS software can also be run in a DOS box with Windows loaded.


Windows 3.x Modem Driver Settings

The modem utility CMENABLE.COM searches for an available COM port or one specified by the user and configures the Xircom adapter hardware accordingly.

CMENABLE.COM Keywords

Keyword	Default	Valid Values

COMx 	AUTO	(x = 1, 2, 3, or 4)

COMIRQ=	Not used	(3 to 15)

COMBASE=	Not used	(0x248 to 0x3F8)

IOWAITSTATES=	Auto	(1, 2, or 3)

MEMORY=	0xD2000	(0xC0000 to 0xE0000)

MEMWAITSTATES=	Auto	(1, 2, or 3)

Modem Driver Example

A typical sequence for loading the modem driver CMENABLE.COM with default configuration settings is as follows:

CMENABLE.COM COMx

where COMx is a COM port value such as COM3 or COM4. If other nondefault configuration settings are used, these must also be stated on the CMENABLE.COM command line.
